Different amounts of "dryness" before they were put into the jars. Target is lower 60% and I'm manipulating the "burping", adding humidity packs, etc to get there.
I do have Bovedas in the "dry" jars but they were not added at the beginning. Even though the cure started dry on some of the jars, they continued to release moisture from within the buds to the surrounding atmosphere. Like a crusty loaf of bread. Wrap it in cellophane and it'll soften right up as the moisture from the core moves outward.
I have not been "burping" the dry jars nearly as long or as often as the "wet" jars.
The middle one actually started about a week earlier and it is cut off on the graph, it has since increased slowly by a couple of percent but it did stay relatively stable. I'm thinking a Boveda pack was added to the green trace on the 4th. I didn't record the date.
I give the jars a shake, open them to exchange the air. So, in part, moving them around seems to release increase the humidity. I'll check if just shaking the jars lightly without opening them has an effect.
edit: just moving the bud around without opening the jar does cause a spike. I'll watch it for a bit to see what it does.
edit: yea, it looks like the jostling of the buds damages enough tricomes to increase the RH in the jar. The humidity does spikes and the resultant RH tends to stabilize at/or near the higher humidity level. Not by much, but it is noticeable.
